| 摘要: |
| 以海藻酸钠为壁材,对挤压凝聚复合法制取天然胡萝卜素微胶囊的主要参数进行了研究。结果表明,壁材浓度、壁材和心材质量比、液滴下落速度对微胶囊化的产率和效率影响较大;其最佳工艺参数为:壁材浓度20 g/L,壁材与心材质量比为3∶1,液滴下落速度为60滴/min,pH为5.0。选用人工挤压乳化法制备天然胡萝卜素微胶囊,与天然胡萝卜素溶液相比,其受外界环境的影响明显减弱,β-胡萝卜素分解速度减慢。 |

| Abstract: |
| Important parameters of natural carotene microencapsulating with the composite method of extrusion and coagulating were researched.The results indicated that concentration of wall material,the proportion of wall material to core material and the dropping velocity had significant effects on microencapsulating efficiency and microencapsulating yield.The optimum technology parameters were obtained through orthogonal analysis as follows:the concentration of wall material was 20 g/L,the weight ratio of wall material to core material was 3∶1,pH 5.0,and the dropping velocity was 60 drops/min.Compared with the natural carotene solution,the decomposition rate of β-carotene was slower and it was not easily affected by environmental factors. |
